The liquid in the salt bath 37 can be stirred through the salt bath stirrer 4, so that salt and water are fully mixed, and the induction speed of the self-adaptive floating ball 8 is faster and the hysteresis phenomenon is weakened through the accelerated fusion mode.
When the salt bath quenching device is specifically used, firstly, the stirring motor 44 is started after salt solution is heated, the stirring main shaft 45 rotates with the stirring wheel 47, the newly added water can be ensured to be quickly and fully mixed through slow stirring of the salt solution, the water inlet valve 24 is opened to enable the water tank 10 to be communicated with the salt bath 37, and a heated workpiece is put into the salt solution through the openable upper cover 39 and stays for a plurality of minutes and then is taken out, so that salt bath quenching of the workpiece can be completed; in the use process, water in the salt solution can be continuously evaporated, and part of the salt solution (comprising salt and water) can be taken away along with the workpiece when the workpiece is taken out, so that the salt and the water are consumed in the use process, wherein the difference is that the salt is consumed when the workpiece is taken out, and the water is continuously evaporated and consumed;
if the proportion of water in the salt solution is reduced, the density and the buoyancy of the salt solution are increased, the buoyancy received by the self-adaptive floating ball 8 is increased, then the self-adaptive floating ball 8 is pushed to float upwards, when the self-adaptive floating ball 8 floats upwards, the overlapping area of the circular hole 19 of the valve clack and the through hole 15 of the bottom table is increased, the water supplementing speed is increased, at the moment, the water supplementing speed is higher than the evaporation speed, the proportion of water in the salt solution is increased again, the buoyancy received by the self-adaptive floating ball 8 is reduced, so that the self-adaptive floating ball 8 sinks until reset;
if the proportion of salt in the salt solution is reduced, the density and the buoyancy of the salt solution are reduced, the self-adaptive floating ball 8 sinks after the buoyancy received by the self-adaptive floating ball 8 is reduced, when the self-adaptive floating ball 8 sinks, the overlapped area of the circular hole 19 of the valve clack and the through hole 15 of the bottom table is reduced or disappears, the water supplementing speed is reduced or water supplementing is stopped, at the moment, the water supplementing speed is smaller than the evaporation speed, the proportion of salt in the salt solution is risen again, and the buoyancy received by the self-adaptive floating ball 8 is increased to enable the self-adaptive floating ball 8 to rise until reset;
based on the above two negative feedback, that is, the adaptive floating ball 8 will eventually tend to an equilibrium state, in which the evaporation rate of water is equal to the water replenishment rate (if the evaporation rate of water is not equal to the water replenishment rate, the ratio of salt to water will necessarily change continuously, and the buoyancy of the adaptive floating ball 8 will not necessarily be stable), and if the water loss rate fluctuates, the water replenishment rate will also follow the fluctuation, so that the ratio of salt to water can be maintained at a stable value;
when the ratio of salt to water is to be adjusted, the adjustment window 42 is simply opened after the tank 10 is removed, and the sleeve is passed through the central circular hole 36 to rotate the hex nut 34.
If the spring seat 27 rotates downwards, the self-adaptive floating ball 8 is pressed downwards, and the overlapping area of the circular hole 19 of the valve clack and the through hole 15 of the bottom table is reduced or eliminated, so that the water supplementing speed is smaller than the evaporation speed, and the proportion of salt in the salt solution is increased; as the proportion of salt in the salt solution increases, the buoyancy of the salt solution further increases, and when the buoyancy is enough to overcome the elasticity of the pre-compression spring 28, the self-adaptive floating ball 8 rises and resets, and finally stabilizes in the balanced state that the evaporation speed is the same as the water supplementing speed, and the proportion of salt in the salt solution is larger than that before adjustment;
if the spring seat 27 is rotated and lifted, the self-adaptive floating ball 8 is lifted due to the reduction of pressure, and at the moment, the overlapping area of the circular hole 19 of the valve clack and the through hole 15 of the bottom table is increased, so that the water supplementing speed is higher than the evaporation speed, and the proportion of salt in the salt solution is reduced; as the proportion of salt in the salt solution is reduced, the buoyancy of the salt solution is further reduced, the self-adaptive floating ball 8 gradually descends and resets and finally stabilizes in an equilibrium state with the same evaporation speed as the water supplementing speed, and the proportion of salt in the salt solution is smaller than that before adjustment;
the stirring wheel 47 is positioned at the bottom of the salt bath 37 and is close to the water outlet of the water inlet pipe 12, so that the water fed in is fast mixed with salt solution, the consistency of the liquid inside and outside the hollow valve box 7 is improved, the liquid entering and exiting the hollow valve box 7 through the thin-sheet type flowing interlayer 16 flows transversely, the self-adaptive floating ball 8 only can lift, and a small amount of longitudinal force borne by the upper hemisphere and the lower hemisphere can offset each other, so that the interference of the flowing liquid on the lifting of the self-adaptive floating ball 8 is avoided.
In the use process, as salt and water are reduced, under the condition of only adding water, the total amount of salt solution is slowly reduced as the proportion of the salt and the water is unchanged, the problem of liquid level reduction is not greatly influenced, the salt is added at intervals, and when the liquid level is changed, the depth of the self-adaptive water supplementing mechanism 1 is controlled through the depth control component 26, so that the influence of the liquid level change on buoyancy is avoided.
As another new embodiment of the invention, if the salt-containing wastewater left in other working procedures is stored in the water tank 10, the period of stopping and adding salt can be prolonged, the waste of water resources can be reduced, and the application can be selected according to the actual working conditions.
